The imago resembles the larva in some particulars, but is 

 winged, and of a mottled brown colour instead of green. It 

 does not blow bubbles. 



The froth evidently serves the purpose of a bath in which 

 the larva may keep cool.

The larvae of crickets and grasshoppers live in or upon 

 the ground, and are thus able to obtain necessary moisture. 

 The cuckoo-spit insect has elected to live high up on plants, 

 and must protect itself against summer heat, which desirable 

 end is attained by the process of blowing bubbles with sap.
